BACKGROUND OF THE INVENTIONThe present invention relates to apparatus for preventing sliding or shifting of cargo being transported in a vehicle. More specifically, the invention is directed to a multi-component platform for use on the the floor of the vehicle such as a pickup truck or van to support loads therein and to prevent cargo transported therein from shifting.
When loads are transported in vans or pickup trucks, it is not uncommon for the loads to shift during acceleration, stopping or cornering of the vehicle. Depending on the type of load involved such shifting can cause damage to the load itself, damage to the vehicle or both. When heavy cargo is being transported such shifting can cause structural damage to the vehicle and in the case of vans, shifting of such loads in the event of sudden stops can also result in injury to the driver.
SUMMARY OF THE INVENTIONThe object of the present invention is to provide a means for securing cargo which is being transported in a vehicle such as a van or pickup truck and to prevent shifting of that cargo. A futher object of the invention is to provide such a securing means which can be used with a variety of vehicles and which is readily adaptable to receive a large variety of cargo types having any number of different shapes and sizes. The securing means is also designed to be easily removable from the vehicle such that the vehicle is not encumbered by the securing means when cargo is not being transported.
The present invention includes a flat platform which is receivable on the bed of the vehicle and which includes a plurality of bores therein forming a pegboard or grid configuration. The bores in the platform are designed to receive securing pegs which prevent movement or shifting of the cargo. As an example, cargo may be placed on the platform and simple cylindrical pegs may be placed in the bores to surround the cargo thereby preventing the cargo from sliding relative to the platform. In the event the cargo does not have a shape commensurate with the grid pattern in the platform, a pair of wedges can be forced between the pegs and the cargo to rigidly secure the cargo. The pegs used to support cargo in this manner can have any variety of shapes depending upon the type of cargo being transported and can include means such that they can be locked into the bores in the platform. Such pegs can also include eye bolts capable of receiving straps or ropes such that cargo can be tied down. Other types of cargo supporting means can also be provided for use in conjunction with the bored platform. For example, plates which have cylindrical projections extending from their bottom surface can be used, wherein the projections are received in the bores and the plates are used to support a variety of types of supporting brackets. Supporting brackets of a wide variety of shapes can be used to hold pipe, lumber, sheet stock, glass, oil drums, flower pots, etc.
The platform may be comprised of a plurality of separable sections which include interlocking complimentary dovetailed projections and notches such that the boards or plates can be secured in assembled relationship when laid on the bed of the vehicle but can be readily removed from the vehicle by disassembly. The periphery of the platform is shaped to approximate the inside periphery of the vehicle such that the platform itself is not shiftable within the vehicle.
The predominant advantage of the present invention is that it provides an inexpensive means for protecting the vehicle, the load and the passengers in the vehicle from damage caused by shifting of loads carried in the vehicle. The platform can be easily placed in the vehicle or removed, is inexpensive and will receive a wide variety of supporting means. The structure of the invention also permits the cargo supporting means used, to be particularly adapted to the primary use of the vehicle.
The following description of the preferred embodiments illustrates several embodiments of the invention for use with a vehicle such as a van or a pickup truck. The embodiments described, however, should not be viewed as limiting the scope of the invention and it should be readily apparent that the apparatus of the invention can include a wide variety of alternative elements. Futhermore, the invention is not limited to use with vehicles such as vans and pickup trucks but could be used with any of a wide variety of vehicles.

DESCRIPTION OF THE PREFERRED EMBODIMENTThe present invention is designed to be used in a vehicle such as thetruck 10, shown in FIG. 1, which has acargo receiving area 12 with afloor 14. The invention includes aplatform 16 which defines a pegboard like arrangement and which is comprised of a plurality of spacedsections 18, 20 and 22. Thesections 18, 20 and 22 are each received in interlocking side-by-side relationship in such a manner in that they are secured together and supported by thefloor 14. Thesections 18, 20 and 22 are connected in interlocking relationship, as best shown in FIGS. 2 and 3, by a plurality ofdovetailed projections 24 extending laterally outwardly from the sides ofsection 20 and received in complementarydovetailed notches 26 in the adjacent sides ofsections 18 and 22.
Theplatform 16 is shown as being constructed from wood and more specifically from 5/8 inch thick waterproof particle board. Of course, the platform may be constructed from any other suitable material such as aluminum or steel plate.
Theperiphery 28 of theplatform 16 defines a contour which is substantially equal to the periphery of thefloor 14. Theperiphery 28 includes a pair of opposedlarge notches 30 which are included to receive the inwardly projectingtire wells 31 of the vehicle. The shape of the periphery of theplatform 16 is particularly adapted for use with a particular vehicle, whereby the relatively close fit of theplatform 16 within thecargo area 12 of thevehicle 10 prevents any sliding movement of theplatform 16 within the vehicle.
Theplatform 16 is provided with a plurality ofspaced bores 32 which are located on, for example, 6 inch centers to form a grid or pegboard like pattern. As shown in FIGS. 3-5, eachbore 32 extends through the platform and includes asteel sleeve 34 located therein. Thesleeves 34 are force fitted into the bores in such a manner that they are tightly received therein. Thesleeve 34 may include a lip around its lower periphery and be crimped around its upper periphery in order to secure it withinbores 32. Strips of relatively thinfoam backing material 29 are secured to the lower surface of theplatform 16 in order to reduce the vibration of the platform with respect to thefloor 14 and in order to reduce the noise incident to such vibration.
The pins orpegs 36 which are best shown in FIGS. 5-7, may have any of a variety of suitable shapes and attachments as will be set forth hereafter. The peg shown in FIG. 5, includes a generally cylindricalupper portion 35 having a relatively large diameter and a smaller diameter lowercylindrical portion 37 which is received in mating engagement in thebore 32. The pegs are generally constructed from a metallic material so as to be rigid and thelower portion 37 has a diameter substantially equal to the inside diameter of thesleeve 34 such that thepegs 36 fit relatively securely within the sleeve. Theplatform 16 is also provided with a plurality of closely spacedbores 27, shown in FIGS. 1 and 2 to facilitate convenient storage of thepegs 36 when they are not in use.
When cargo, such as box B shown in FIG. 8 is placed in the vehicle, a plurality ofpegs 36 can be placed around the cargo in thebores 32. If necessary, a pair ofwedges 38 can then be forced between thepegs 36 and the box B in the manner shown such that the box B is firmly secured between the pegs and is prevented from sliding movement within the vehicle. Wedges can also be used on two sides of the box B rather than on just one side as shown in FIG. 8. Of course, if the cargo is of a size commensurate with the spacings of thebores 32, it may be necesary only to place thepegs 36 in thebores 32 to secure the cargo and thewedges 38 would be unnecessary. Thewedges 38 can also includebores 31 extending therethrough for receiving theupper portion 35 of the pegs in order to secure the wedges in place with respect to theplatform 16.
Use ofpegs 36 such as those described is generally most desirable where the cargo has a relatively low center of gravity such that if the cargo shifted it would tend to slide along the platform rather than turn over. On the other hand, if the cargo is of the type which could tip over, an alternative type of pegs should be used. Two such alternative embodiments of thepegs 36 are shown in FIGS. 6-7. The pegs 36', shown in FIG. 7, are illustrated as including a cylindrical upper portion 35' and a smaller cylindrical lower portion 37' which is received within thebores 32. The lower portion 37' is split in a longitudinal direction along the line 41' such that it can expand or contract in diameter and further includes a tapered bore 43' therein. The peg 36' is provided with an axially extending central bore 48' capable of receiving an eyebolt 46' therethrough. The eyebolt 46' includes a threaded lower portion 45' threadably received in a tapered member 47' which is in turn receivable within the tapered bore 43'. The eyebolt 46' can cause the tapered member 47' to be pulled into the tapered bore 43' to cause expansion of the lower portion such that it may be locked in thebore 32. The eyebolt 46' may then receive ropes or other securing means which can be used to hold cargo and prevent it from shifting. For example, a plurality of such pegs can be spaced around cargo such as the motocycle, as shown in FIG. 14, and lines which extend over the cargo can be secured to these pegs. FIG. 6 illustrates another embodiment of thepegs 36 which can be used to secure cargo. Thepeg 36" shown therein includes a lowercylindrical portion 37" and a threadedeyebolt 46" which is received within aconcentric bore 48" extending through and co-axial with thepeg 36". Thelower portion 37" is comprised of resilient material such as rubber and is receivable within thebores 32. Ametal washer 43" having a threaded bore therein is secured to the lower surface of the resilientlower portion 37" and receives the threadedeyebolt 46". When thepeg 36" is inserted into the bore, theeyebolt 46" can be tightened to cause radial expansion of theresilient portion 37" such that thepeg 36"is securely received within thebore 32.
FIG. 9 illustrates an alternative embodiment of the cargo securing means of the present invention wherein bracket means 50 are provided to support elongated items such as lumber and to prevent shifting movement of such items in the vehicle. More specifically, the supporting structure shown in FIG. 9 includes aplate 51 which is received in flat engagement with theplatform 16, theplate 51 having a plurality of downwardly extendingpegs 52 integrally connected to and projecting from its lower surface. Thepegs 52 are properly spaced so as to be receivable within the spaced bores 32 such that the pegs can prevent sliding movement of theplate 51 with respect to theplatform 16. The upper surface of theplate 51 rigidly supports theangular bracket 50. Theangular bracket 50 is provided with a pair of upwardly extending arms for receiving lumber therebetween. As an alternative embodiment of that shown in FIG. 9, it would also be possible to merely provide theangular bracket member 50 with downwardly extendingpegs 52 in such a manner that the angular bracket could be directly supported by theplatform 16.
FIG. 10 illustrates another embodiment of the invention analogous to that shown in FIG. 9 but designed to support sheets of meterial in a vertically positioned relationship. A flat supportingplate 54 is provided having a plurality of downwardly extendingpegs 52 secured to its lower surface and receivable inbores 32 in theplatform 16. A plurality of elongated upwardly extendingbrackets 56 are rigidly secured to theplate 54 and includearms 58 capable of supporting sheet material in a vertically extending position.
FIG. 11 illustrates another alternative embodiment of the invention wherein a cargo securing means is positioned to support a cylindrical drum and prevent sliding movement of said drum. The cargo supporting means shown in FIG. 11, includes a flat supportingplate 60 which includes a pair of downwardly extendingpegs 52 projecting from its lower surface and spaced so as to be receivable inbores 32 in theplatform 16. Theplate 60 has an L-shaped configuration and supports an angulardrum supporting bracket 62. The supportingbracket 62 rigidly connected to the inside surface of the L-shapedplate 60 and extends vertically therefrom to prevent sliding movement of said drum. Theangular bracket 62 defines a right angle such that it abuts the drum on two sides and is thus capable of preventing movement of the drum in two directions. However, if necessary, a second such support means can be placed on the opposite side of said drum to secure the drum against movement in all directions.
FIG. 12 shows an embodiment of the invention closely analogous to that shown in FIG. 9 but wherein a U-shaped bracket means 66 is positioned for supporting the ends of such items as pipe or other elongated cylindrical objects. TheU-shaped bracket 66 is supported by a flat supportingplate 51 in the same manner that thebracket 66 is supported from theplate 51, and theplate 51 is prevented from sliding movement with respect toplatform 16 by a pair of downwardly extending pegs 52.
FIG. 13 illustrates yet another embodiment of means for supporting sheet material in a vertically extending position. An L-shapedbracket 68 is rigidly secured to a flat supportingplate 70 which is in turn secured against movement with respect to theplatform 16 by a plurality of spaced downwardly projectingpegs 52 received inbores 32. The L-shapedbracket 68 is secured to theplate 70 in such a manner that thebase 72 of the L-shaped bracket is cantilevered to extend beyond the edge of theplate 70 and the vertically extendingportion 74 of the bracket is integral with the outwardly extending end of the bracket. The peripheral edges of the L-shapedbracket 68 includechannels 76 for receiving sheet material therebetween. Thebracket 68 also has a possible alternative function in that the vertically extendingportion 74 could be placed in abutment against cargo, such as large boxes, etc., to prevent movement of such cargo.
Additional embodiments of the invention can also be provided as supporting structures for holding specific goods therein or for supporting particular types of cargo. For example, FIG. 14 illustrates amotorcycle mounting rack 80, comprising a flat supporting plate 82 and a rigidly attached elongatedU-shaped bracket 84, which further includes a plurality of downwardly extending spacedpegs 52 projecting from its lower surface and receivable in the spaced bores 32 in theplatform 16. The mountingrack 80 is thus secured in the van or pickup truck against shifting or sliding movement. The motorcycle can be tied down usingropes 86 or straps received inpegs 36' or 36" to prevent any movement of the motorcycle during transportation.
FIG. 14 also illustrates the use of aramp 90 for loading a motorcycle into a van or pickup, wherein the end 92 of theramp 90 extending into the van or pickup truck is provided with a plurality of spacedprojections 52 extending downwardly and receivable in the bores in the platform. The platform thus facilitates stabilization of the ramp during the loading process.
FIG. 15 illustrates one more additional embodiment of the invention wherein abasket 94 is secured to theplate 16 by means of apeg 52 rigidly secured to the basketbottom plate 96. Baskets or buckets of this type are particularly useful, for example, for florists wherein flower pots may be supported in the baskets during transit.
ResumeThe cargo restraining assembly of the present invention thus provides a means to secure cargo in a vehicle which is readily adaptable to receive and to support any of a large number of types of cargo. The restraining assembly also includes a platform which is easily removable from the vehicle but when in place, is secured such that is does not slide with respect to the cargo floor of the vehicle and also includes means which substantially reduce any vibration of the platform. The assembly is relatively inexpensive and uncomplicated yet it effectively protects the vehicle, the load and the passengers from any damage it might be caused due to shifting or overturning of the cargo.
